Accommodating Intraocular Lenses

a technology for intraocular lenses and lenses, applied in intraocular lenses, prostheses, medical science, etc., can solve the problems of preventing widespread commercialization of such devices, reducing the ability of patients, and unable to accommodate patients, so as to reduce compressive forces, increase the cross-sectional area of the haptic, and increase the internal volume of the haptic

Abstract

An accommodating intraocular lens includes an optic portion a haptic portion and a backstop. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. The backstop provides support to the haptic so that bulk translation of the haptic is prevented in response to the forces applied by the capsular sac.

[0002] The present invention relates to intraocular lenses (“IOLs”) having optical parameters that are changeable in-situ. More particularly, the invention has application in IOLs for in-capsule implantation for cataract patients or presbyopic patients, wherein movement of the lens capsule applies forces to a circumferentially supported haptic to more efficiently induce trans...
